Does the 4.7"/5.5" and 6/6+/6S/6S+ give you any advantage in term of productivity over the iPhone 5S/SE and their 4.0" size? Whether this be letting you type better in Words, using Excel, and making PowerPoint, letting you read news article or literature better, surfing the web, watching videos, using emails better etc...anything...I mean in a productivity in context and not luxury context like "oh my video is bigger" etc. Also, technology, does the iPhone 6/6+/6S/6S+ have any technologies over the 5S/SE that also increases your productivity? just give me your first hand account, second hand account, or from what you read in reviews or elsewhere. Thx.
